Gone are the days of the granola fashion label, where sustainable materials tended to mean lackluster design. The new age of eco designer labels are sitting alongside mainstay ready-to-wear labels in Nordstrom and Revolve Clothing with a posh aesthetic to match. Enter Amour Vert, the entirely sustainable label founded in 2010 by Christoph Frehsee and Linda Balti, whose mission is to change not just the way we dress but also how the fashion industry produces its clothes.

After Kwong was drafted to help with the brand’s lookbook for fall, the Columbia grad wanted to get more involved with the company’s commitment to protecting the environment. “I was working in landscape design and the Buy a Tee, Plant a T(r)ee program really resonated with me,” says the budding eco-philanthropist. “What I bring to the table is a strong ‘fashion’ point of view from living in New York City and having my finger on the pulse of the trends and changes in the industry.” It’s no surprise, then, that Amour Vert has attracted a strong celebrity fan base, including Blake Lively, fashion scribe Olivia Palermo, and model Dylan Penn. The item du jour among this set? A simple striped tee that evokes both the effortlessness of Parisian cool girls and the modern look of Manhattanites—a T-shirt, sure, but perhaps the chicest T-shirt around. “I cannot stress how cozy our fabrications are!” says Kwong. “For women like Blake, who are constantly on the go, a brand that offers both style and comfort is a no-brainer.” [#image: /photos/589191ad85b3959618474dfa]|||Dylan Penn|||On Earth Day tomorrow, the label is letting everyone get a taste of eco-elegance through the tag #PlantATreeAV @amourvert and will plant a tree for every Instagram snap of a tree with the tags. “We’ve challenged ourselves to plant 100,000 trees this year,” says Kwong, “and we are well on our way having planted over 27,000.” Talk about a lot of green.
